I whant to try LDAP on a OpenSuse 10.3 Linux too but dont find a good help. There is an HowTo http://en.opensuse.org/Howto_setup_SUSE_10.1_as_Samba_PDC
. But that one does not work, becouse 10.3 is no more compatible with smbldap-tools package.
Then i tried do build an LDAP-Server with the Tool from OpenSuse- Yast2 - "Netzwerkdienste" - LDAP-Server but there is no Help so i dont know what i have do do with it...
P.S. i have searched by google and co the hole day, so please dont say: Why dont you google for...
I hope someday i could help you!
